九种雌激素化合物的辐照降解研究

Radiolysis of Nine Estrogens by ^(60)Co γ-Irradiation

研究了60Co源γ射线辐照对9种常见的雌激素化合物的降解作用,考察了辐照剂量、雌激素初始浓度以及不同添加剂对辐照率的影响。结果表明,辐照可以有效降解雌激素化合物,降低雌激素的初始浓度,增加辐照剂量可提高降解率。添加剂水和H2O2都可以促进雌激素的降解,而正丁醇则会抑制雌激素的降解,且反应体系中添加剂体积分数越大作用越明显。

9 estrogens were degradated by γ-radiation from ^60Co.The effects of radiation dose,initial concentration of estrogens and additives on the degradation efficiency were studied.The results showed that γ-irradiation could effectively degrade estrogens.The lower the initial concentrations of estrogens were or the higher the irradiation dose was,the higher the degradation efficiency was.The addition of H2O and H2O2 could increase the degradation efficiency of estrogens;however,butyl alcohol inhibited the degradation of estrogens;and the higher the volume fraction of the additives was,the more obvious effect on estrogens degradation was.
